I like & have used many knives through out my life.
Even wore out a few.
I always have a pocket knife or two on me to help with my daily chores. Give me a good USA blade. I like them all; tactical, lock, fixed, serrated blade, tanto blade, etc.
If I had to pick just one, give me a W.R. Case & Sons Cutlery Co. knife.
When it comes to pocket knives I'm a traditionalist. To me, nothing compares to that classic American pocket knife design; Stockman, Trapper, Peanut, Congress, etc.
I believe I feel so strongly about traditional pocket knives is because my 1st knife given to me, at age 8 (I'm 45 now), by my dad was a Case. Although I've retired that same knife to my displayed collection in the living room years ago it's still usable and very sharp even after Hell & back.
